Can I show that Biblically? Sure. It permeates Old Testament culture.
I looked up kneel(ing) and bow(ing) in the good old BibleGateway Keyword Search, and found so many references it would be exhausting to list them all.
And these are all examples approved by God! Not one of them is condemned or reproved!
Genesis 23:7 Then Abraham rose and bowed down before the people of that land.
Genesis 33:3-7 Jacob bowed down to the ground seven times as he approached his brother Esau.
maidservants and their children bow down to Esau

1 Kings 1:15 Bathsheba bows low (face to the ground) and kneels before the aged king David

Moses bows down to father-in-law; Ruth bows down to Boaz;

the whole assembly bows low and prostrates before David;

OK, pretty obviously the patriarchs, prophets, and kings knew about the commandment not to bow down and worship anything or anybody but God. But here they are bowing, kneeling, and prostrating, and God is not offended. Why?
Because the commandment clearly forbids bowing and worshipping a creature as the Creator--- in other words, adoring; it does not forbid kneeling or bowing (to king, prophet, father, husband or brother) as a form of honor.
The commandment does not prohibit kneeling or bowing to give honor. It prohibits, specifically, adoration toward anyone but Almighty God.
Now heres an interesting episode:
1 Kings 2:19
When Bathsheba went to King Solomon to speak to him for Adonijah, the king stood up to meet her, bowed down to her and sat down on his throne. He had a throne brought for the kings mother, and she sat down at his right hand.
Heres the King bowing to his mother. Does that mean shes equal to God? No. It doesnt even mean shes equal to the King. It means hes pleased to honor her because of her royal dignity, her relationship as Queen Mother.
As our mindset gets further and further from traditional custom and culture, it gets harder and harder to grasp what was once the universal language of physical gesture (the salute, the tip of the hat, the bow, the genuflection, the handclasp, the curtsey, the kiss) and put each expression in its proper perspective.
That's a Biblical truth to ponder and appreciate. As I live, I appreciate it more and more.
Does every tenet of your religion require such a tedious explanation and why do you bind yourself to a lawyer-esque tact of defending your Faith?
It is so simple, my friend. Put your Faith in Christ and his work on the cross, and free yourself from all that unnecessary gobble-dee-gook.
